Hi Brad, hi Enis,

ok, so one possible way should thus be to use the _cleanup_ec2() function before creating an AMI via the amazon console and the second option perhaps is this share-a-cluster functionality.

About the latter: sorry, I tried to find out what it really does, but did not find any documentation of it. So, how does this share-a-cluster functionality work in principle? If it does not create AMI, does it just create snapshots of the individual disks that users have to mount (manually) or ... ? My point here is: I need to make a modified version of GalaxyCloudman available (i.e. one that contains the CADDSuite tools). I do not just want to share an _instance_ (a running cluster) but a cloudman image (as an AMI or by some other means) that includes all my tools, so that other users can easily start their own server.

If you do indeed have a description of this somewhere that I just did not find, then I am sorry but would be grateful for a link ;-)

However, I would like to share the modified GalaxyCloudman version with
other people and therefore I do have to create an AMI.

What Enis was suggesting is using the share-a-cluster functionality
built into CloudMan. This bundles your data volumes as snapshots and
prepares a sharable cluster than anyone can initiate.

In the CloudMan interface, there is a little green button next to the
cluster name that enables this. That is definitely the easiest way to
share and distribute modified CloudMan versions.

Ok, I will try to make this work somehow ... but I guess there are no
immediate clues as to what could have gone wrong? Or do you have any
ideas what I should try?

After CloudMan boots once, you need to clean up some files before
preparing an AMI. This is the automated code we use to clean up for
prepping CloudMan compatible AMIs:


Be careful if you run that directly. It runs immediately before bundling
and removes the ssh keys (so you don't have a backdoor to the AMI you
are distributing) so you want to do it as the last thing. It also
assumes you have unmounted all of the associated Galaxy data libraries.

Hope this helps,
